Carb tuning

[sho061]

Hey guys. I have a 00 220 with fmf pipe and spark arrestor. I ride in the woods about 1500ft tight single track. Running 50:1 fuel mix.

I need to tune my carb and rejet. I don't know if it has ever been done. The carb is stock. I was wondering what you guys would suggest for a jetting kit/size.

Take the carb apart, find out what the jets are and then go buy leaner/richer as needed . . . My local shop sells mains for about $3.00 each.

I left the jetting stock on my 03 when I went to the FMF Rev pipe and spark arrestor (fuel mix 60:1). It seems to work alright until I ride it at really high elevations like 8000 ft.

What is the bike doing, running lean or rich or what?
